Introduction to OLED Technology
OLED screens are made up of an emissive technology, where each pixel emits its own light when an electric current is passed through it. This is in contrast to traditional LCD (Liquid Crystal Display) screens, which rely on a backlight to illuminate the pixels. The emissive nature of OLED technology allows for true blacks, as pixels can be turned on and off independently, resulting in an almost infinite contrast ratio. This, combined with faster response times and wider viewing angles, makes OLED screens a favorite among display enthusiasts.
What is Screen Burn-in?
Screen burn-in, also known as image retention, refers to the permanent ghostly impression of an image that remains on a screen after the image has changed. This phenomenon occurs when a static image is displayed on the screen for an extended period, causing the organic material in the OLED panel to degrade unevenly. As a result, the affected pixels may exhibit a noticeable change in brightness or color, leading to a permanent “burn-in” of the image.
Causes of OLED Screen Burn-in
Several factors contribute to the likelihood of screen burn-in on OLED displays. Static images are the primary culprit, as they cause the same pixels to be active for extended periods. This can include elements like navigation bars, logos, and icons that remain on the screen for a long time. Additionally, high brightness settings can accelerate the degradation process, as higher currents are passed through the pixels. Lower quality OLED panels may also be more prone to burn-in due to the use of inferior materials or manufacturing processes.
